Flipped 3 pennies and did this 100 times. You got 3 tails 40 times. What is the difference between the experimental probability of getting 3 tails and the theoretical probability? (simplified fraction)

Answer 1

The theoretical probability of getting 3 tails when flipping 3 coins is (1/2)^3 = 1/8.

The experimental probability of getting 3 tails in this case is 40/100 = 2/5.

The difference between the experimental probability and theoretical probability is 2/5 - 1/8 = 16/40 - 5/40 = 11/40.

Therefore, the simplified fraction representing the difference between the experimental probability of getting 3 tails and the theoretical probability is 11/40.
